- SULFUR CANDLE.

SPECIFICATION forming part of Letters Patent No. 539,061, dated May14,1895. Application filed July 24,1894. steam. 51:34am. (N0 specimens.)

To all whom it WLLZy GOTZ /CBKZM j Be it known that I, OHARLEsTHoMAsKING- ZETT, a subject of the Queen of Great Britain, and residing'atElmstead Knoll, Ghislehurst, London, county of Kent, England, haveinvented certain new and useful Improvements in Fumigators, of which thefollowing is a specification. r

My invention relates to that class of devices often known as fumigatorsor fumigating can; dies, commonly made of sulphur or a mixture thereof,and havinga suitable container adap ted to keep the sulphur fromdispersion-as it melts under the-heat of its consuming flame. In the useof such fumigators itis desirable to supply to the gases or fumesevolved by combustion an aqueous vapor for the formation with such gasor gases of the desired sulphur ous acid gas. Such aqueous vapor isordinarily furnished by burning the fumigator in immediate proximity toa body of water, commonly by placing the fumigator in the water so as tobe almost completely immersed therein. Then this is done it is desirableor necessary to the complete combustion of the sulphur to surround thefu migator, or that portion thereof which is immersed, with awater-proof covering or container in order to prevent the wetting of thesulphur by the water which would prevent its perfect combustion, orcause spitting with consequent danger of starting fires. In order thatthe heat of combustion maybe readily communicated to the water for theproduction of an aqueous vapor as aforesaid, such water excludingcontainers havehereto fore been made of a good conductor of heat ofrigid non-flexible material, such as commercial tin plate, but theexpense of such vessels or containers is a material objection to theiremployment, oftentimes exceeding the value of the candle.

It is the object of my present improvement to supply a fumigator incasedin a water-excluding container of very cheap character and which is abetter conductor of heat and which will better promote the'generation ofaqueous vapor, when the fumigator so incased is immersed in water, thanthe tin vessels or containers above mentioned. To this end I combinewith the fumigator of sulphurjor a mixture thereof, a sheet of metallicfoil in such manner that all parts of the fu'migator to be immersed inwater will be covered and protected. The foil is preferably applied in asheet with the middle of the latter upon the bottom of the furnigatorand its edges folded or bent up upon the sides of the candle. The

extreme edge of the sheet of foil may be bent over upon the top surfaceof the fumigator, or may terminate at or above its upper edge, as found.most desirable, or may on its upper margin be perforated or serrated.The covering of foil may,'however, be formed upon a suitable mandrel andthe sulphur or mixturethereof, while in a fiuid'condition may be pouredinto the container thus previously formed.

The fumigator may be supplied with an ig-' niter embedded in the body ofthe candle in the usual manner, or such igniter may be com- .bined withthe fumigator by being placed upon its exterior with its ends projectingabove the top of the fumigator and the sheet of tin foil then applied tothe exterior as aforesaid; or the igniter may be laid in a U- shapedstrip within the container and having its ends projecting above the edgethereof and the molten sulphur then poured in upon the igniter. or theigniter may take the form of a strip or circle stretched across or overthe face of the fumigator and secured by means of the edge of the foilwhich is folded over the edges of the strip. WVhile the container thusproduced may be very readily combined with the fumigator, and is veryinexpensive, it will nevertheless sufliciently protect the sulphur fromthe water and will readily conduct heat to the latter for the purposealready described. I

Such being the generalnature of my improvements, I have shown in theaccompanying drawings means for carrying the same intopracticahe'ffect,without limiting my invention in its usefulapplications tothe particular constructions'or shapes which, for thesake of illustration, I have delineated.

In said drawings, Figure 1 is'a perspective View of afumigator embodyingmy invention. Fig. 2' is avertical sectional view of the same. Fig. 3 isa perspective view of the fumigator, immersed in water and ready forcombustion. Fig. 4 is a vertical sectional View of another form offumigator also embodying my invention. Fig. 5 is aplan view of the same.Fig. 6 is a perspective view of a container'of tinfoil formed upon amandrel and ready to receive the sulphur. Fig. 7 is a perspectivevi'ewof a fumigator, with its igniter,'and asheet of tin-foil about tobe applied thereto to form a container. Fig. 8 is aplan view of a fumigator having applied thereto a circular igniter secured by the edge ofthe container. Fig. 9 is a side view of a fumigator having its containerserrated on its upper edge.

Referring to the drawings, 1 indicates the body of the fumigator orcandle formed of sulphur or a mixture thereof.

2 is a container of tin or lead foil applied to the exterior of thecandle so as to cover and exclude water from its bottom and sides. Suchcontainer may terminate just at the upper edge of the candle, or may befolded over upon the top surface of the latter as indicated at 3, inorder to better prevent the edge of the container from being caught andstripped or rubbed from the face of the candle. The container may bepreliminarily formed in any.

suitable manner as indicated in Fig. 6, or it may be applied to theexterior of a candle in the form of a sheet as indicated in Fig. 7, bythe numeral 4.

The igniter for facilitating the ignition of the candle maybe formed ofbobbinet or other foraminated or suitable material embedded in thecandle and projecting above the top thereof in circular or other form asindicated at 5, in Fig. 4, or said igniter may be in the form of a stripas shown at 6. This strip may be situated upon the exterior of thecandle, passing around the bottom thereof with its ends projecting asshown in Figs. 1 and 2. In such case the igniter lies immediately uponthe inner surface of the container, and may be placed in the latterbefore the sulphur is poured in. The ends of the strip 6 are coated withsulphur, and, when about to be ignited,

may be bent upward slightly above the top of the fumigator, as seen inFig. 3, so as to burn readily. These ends are rendered by their sulphurcoating very stiff and brittle and are liable to become broken off, orlose their film of sulphur, unless some means is adopted for theirprotection. According to my invention said ends lie fiat upon the top ofthe f umigator, Fig. 1, whenthe latter is packed for trans- As shown inFig. 8 the igniter may be in annular form, engaged all around its edgeby theJoent-over edge of the container- When 'thus constructed theigniter is very efiectively protected against being broken in pack ingand transportation.

Then it is desired to burn the fumigator, it is placed in water in asuitable vessel 7, as seen in Fig.3, the top of the candle being levelwith or only slightly above the surface of the water. The igniter 6 isthen ignited and the combustion of the candle begins. As

the flame reaches that portion of the foil container the outer surfaceof which is in contact with the water, heat is rapidly conducted throughthe foil and abstracted by the water, and'to such a degree that themelting of the foil so in contact with and excluding the water isprevented. A thin film of sulphur may be left unconsumed upon the innerface of the container, but otherwise the sulphur will ultimately beentirely consumed. The considerable amount of heat thus imparted to thewater around the container generates aqueous vapor which rises andmingles with the fumes from the burning sulphur, producing the desiredgermicidal sulphurous acid.

I find that foil suitable for the above de scribed use is ordinarily tinfoil, or tin and lead (alloy) foil, or common lead foil.

Instead of applying the middle of the foilsheet to the bottom of thecandle, the foil may be wound around the candle and its edgesinterlocked along the side and bottom of the latter to form a seam whichwill be practically water-tight.

By the use of my invention the candle provided with its container whilehaving the above described advantages, will also be neat, and lighter,and occupyless room in packing than as now put up. With all sizes ofcanmaterial which occupy considerable space,

the metallic foil may be kept in stock in flat condition ready forimmediate use or to be shaped or formed upon fumigators of any desiredsize.

Should the metallic foil container or its joints or folds fail to beabsolutely water-tight, the water will be excluded from the fumigator bythe film of sulphur which will be left unconsumed over such opening oropenings.

I claim-- 1. A fumigator of sulphur or a mixture thereof, incased in acontainer of metallic foil, substantially as set forth.

2. A fumigator consisting of a candle of sulphur or a mixture thereof,having an igniter around its exterior with an end or ends above the topof the candle, and a container of metallic foil enveloping the bottomand sides of said candle and igniter, substantially name in the presenceof two witnesses.
